| Hazard Information | Back Directory | [General Description]
A clear brown to black liquid with a characteristic phenoxy odor. Primary hazard is threat to the environment. Immediate steps should be taken to limit spread to the environment. Easily penetrates the soil to contaminate groundwater and nearby waterways. | [Reactivity Profile]
This material is incompatible with strong oxidizers. | [Air & Water Reactions]
Completely soluble in water. | [Hazard]
Irritant by inhalation.
| [Fire Hazard]
Flash point data for this compound are not available. 2,4-D SODIUM SALT is probably combustible. | [Chemical Properties]
Crystalline solid. Decomposes at 215C.
Slightly soluble in water.
| [Production Methods]
The commercial production of 2,4-D sodium begins with purified 2,4-D acid, produced via the standard phenoxyacetic acid route involving chlorination of phenol and etherification with monochloroacetic acid. Once the free acid is isolated and refined, it is dissolved in water or a mixed solvent and neutralised with sodium hydroxide, forming the sodium carboxylate salt under controlled pH and temperature to avoid excess base or unreacted acid. | [Mechanism of action]
Selective, systemic, absorbed through roots and increases biosynthesis and production of ethylene causing uncontrolled cell division and so damages vascular tissue. Synthetic auxin. | [Pesticide Type]
